4 ROLLING-MILL GUIDE.

' Application filed February nue, Johnstown, Penns'ylvania,) have invented certainnew and useful Improvetion.

ments in Rolling-Mill Guides; and I do hereby declare the following tobe a full, clear, and exact description ofthe inven tion, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to rollingmillguides with special reference to aconstruction that allows the adjustment of. same around theirlongitudinal axes to provideforshght1rregularit-ies due tomisplacem'ent, malformaw tion, wear or' other causes. Although myinvention isapplicable to. various formsof.

guides, such as straight guides which do' not produce a twist in arolled bar,,it is particularly adapted to what is known as twist guidesand is so illustrated herein.

()ne of the features of my invention conslsts. generally in mounting theguide in' a holder. which is adapted to be rocked'or rotatedapproximately around its axis on its curved or semi-circular base andheld in position by screws, wedges orother means, thus obviating thenecessity of rotating the guide by itself, and also allowing the working portions of the guide to be made much smaller and consequentlycheaper and easier of replacement.

Having thus given a general description of my invention, I will now, inorder to make the matter more clear, refer to the annexed sheet ofdrawings, which forms part of this specification, and in which likecharacters refer. to 'like parts.

Specification of Letters Patent. Patented Dec, 16, 1919.

18, 1918, Sei-ia1No.217,741'.

Referring now to the characters of reference on the drawings :1 is thehousing of the receiving pair of rolls, 2 are the rolls thereof providedwith a pass or groove 3. 5 is the twist guide, the tapered end of whichis 4, adapted to fit in thecurved space between the two rolls. Thisguide is prefer ably made .in pairs ortwo portions which can beseparated to allow a cobble to be easily removed, and their interiorsurfaces are formed with a twist or spiral, adapted to receive what isknown as an oval or bar -of oval cross-'sectiom; the major axis of pass3 of the'rolls, and the guide twists it until its major axis issubstantially vertical and adapted to enter the pass of the next set ofrolls, which may be either round,

square or approximately round, or square. For this-purpose it isnecessary that the guide should lead andhold the bar with the longeraxis of its section upright immediately next to the pass in order thatthe reducing action of the rolls shall be accomplished in the directionof the major axis of the cross section of the bar. Secured to the rollhousings is the guide rest bar 6, and on this is-mounted the casing 7,provided with a projecting portion 8, adapted to fit in acorresponding'groove in the rest bar and secured thereto through thehole 9 by means of the bolt 10, the bolt'head resting in the recess 11in the' casing. 12 are upwardly extending ears or lugs of the casing. 13are holes in-the cars 12, whereby the casing may be lifted fromposition, or a bar may be introduced through the holes to 'wedge out thecross bar 15. 14 are grooves or recesses in the inner faces of the ears12. 15 is a cross bar, the ends of which are adapted to be seated withinthe grooves 14.

. 16 are wedges adapted to be inserted between the cross bar 15 and theu per surfaces of the guide holder 17. he guide holder 17 fits looselyin the casing 7 and is I! provided with a curved lower portion 18, whichis slightly smaller than and adapted to loosely fit within the curvedrecess 19 in the casing 7. The guide holder is further provided withprojecting flanges 20 adapted to contact with the ears of the casing andprevent displacement of the guide holder, and has a groove or recess 21adapted, to receive the guides '5. Vertical grooves 22 are also providedin the insides of the guide holder 17 adapted to receive the projections23 formed on the guides 5 to assist in holding them longitudinally inposition. 24 are of Fig. 1, '27 is a receiving guide adaptedtoi'eceivethe bar as it issues from the adjustable twist guide 5 andpass it into the rolls on the left-hand side, the bar being indicated bythe broken line and the direction of its movement by the arrows thereon.

My-rolling mill guide maybe axially a djusted in position by looseningthe two wedges 16 by driving them backward and then rotating-the guideholder 17 either by hand or by light taps of a hammer or preferably bysetting one of the wedges in position' desired and then driving theother wedgeinwardly until both wedges become tightand the guide holderis in-th'e required position, this action causing the guide holder torotate substantially around the guide axis by reason of its curved lowersurface 18,,

which is substantially a semi-circle with its center as the guide axis,this convex surface 18 being adaptedsto fit and 'bes uppolted within thecurved recess 19 inthe casing 7. Slight and accurate adjustments ma bemade in this way and when the wedges are both driven tight, the guideand guide holder 'are firmly secured in position. I

Although I have described and illustrated my invention in considerabledetail, I do not wish. to be limited to the enact and speeificdetailsthereof as shown and described, but may use such modifications in,substitutionsltor, or equivalents thereof, as are. eInb need within thescope of my invention, as pointed out in the claims.

Having thus described mv invention, what I claim and desire to secure byLetters Patent is:

1. A rolling mill guide provided with a guide holder-and means vtorsecuring said guide therein, said guide holder being mounted in a fixedcasing and provided with means for rotatively adjusting said guideholder and contained guide in said casin 2.
